10 cool things to do in London this weekend

The Where Are You? travel competition: July 2017

Many mysteries lie buried in these golden sands, as little is known about this ruined rock city, which lies halfway between two better-known desert landmarks. A combination of a dry climate and a lack of local visitors, due to rumours of an ancient curse, has enabled this 1st-century BC wonder to survive relatively undisturbed. There are water wells and more than a thousand tombs carved into its sandstone cliffs and canyons, some standing over 40 metres tall, many with inscriptions about their occupants. While excavations are ongoing, a lot of the site is still largely unexplored by archaeologists. Although it now lies silent, this was once part of a dynamic and innovative civilisation, founded by a nomadic tribe and comprising early explorers, far-ranging spice traders and skilled masons. Despite never featuring on any of Indiana Jones' action-packed itineraries, the city was written about in the 10th century, long after it had been abandoned, and visited by Victorian explorer Charles Doughty, who wrote: 'Sultry was that midday winter sun, glancing from the sand, and stagnant the air, under the sun-beaten monuments.'
